With the pressure washer working as normal, it is not advisable to reduce the
pressure on the unloader valve (by twisting adjuster anti-clockwise) for long
periods of time, as this redirects a proportion of the water flow back through
the by-pass system, which increases the temperature of the pump. If the
pressure is too high, it can be reduced slightly by reducing engine speed
marginally (from 3400rpm max to around 2800rpm). If the pressure needs to
be reduced further, it is recommended to use a larger nozzle size to reduce the
pressure.
If the nozzle size is too small, it will reduce the water flow and activate the by-
pass system, which will reduce the pump life, as it will run at a higher
temperature.
The pressure washer pump will move the same volume of water whatever the
pressure. The pressure is created by the size of the nozzle. The smaller the
nozzle the higher the pressure. It is important not to go too small as this will
reduce flow, which reduces cleaning efficiency and pump lifespan.
8. SPRAY TIPS
8.1.
How to use spray tips
8.1.1.
The quick–connect on the nozzle extension allows you to switch between four different
quick connect spray tips.
8.1.2.
The spray tips can be changed while pressure washer is running once spray gun
safety
lock is engaged.
8.1.3.
The spray tips vary the spray pattern angle as shown above.
The high pressure stream of water that this equipment produces
can cut through skin and its underlying tissues, leading to serious
injury and possible amputation.
8.1.4.
NEVER exchange spray tips without the trigger safety lock engaged on the spray gun.
8.1.5.
DO NOT twist spray tips while spraying.
